Origin of aperient

1620–30; < Latin aperient- (stem of aperiēns opening, present participle of aperīre to open), equivalent to aperi- (apparently ap-, variant of ab- ab- + -eri-) + -ent- -ent; the base -eri-, perhaps with an earlier shape *wery- or *twery-, occurs only in this verb and operīre to close (see cover, operculum)
Also called aperitive.
